iMPROVEMENT IN HARVESTERS.

Specification forming part of Letters Patent No. 206,425, dated July 30, 1878; application filed May 17, 1877.

To all whom it may concern:

Be it known that we, ()RVILLE OOOLEY and MYRoN M. OLIVER, of Brockport, in the county of Monroe, and STEPHEN E. SHERWOOD, of Oonesus, in the county of Livingston, both in the State of New York, have invented a new and Improved Harvesting-Machine; and we do hereby declare the following to be a full and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which Figure 1 is a plan of the inner end of the machine, showing certain parts in section. Fig. 2 is a vertical section of the same, taken in lineax of Fig. 1; and Fig. 3 is a horizontal section of the frame-casting, showing the arrangement of the several pinionshaft standards.

Similar letters of reference in the accompa nying drawings denote the same parts.

The object of this invention is to improve the construction of grain-harvesters, so as to attain, to as great an extent as possible in one machine, extreme simplicity, lightness, and strength, an equal balancing of the machine, and a complete adjustability of all the parts with relation to each other and with reference to the work to be done.

To this end the invention consists, first, in

- the construction of the main frame; secondly,

in the mode of supporting the pinion-shafts; thirdly, in the combination of the main pin ion-shaft with the driving-shaft of the cutter and the driving-shaft of the rake, in such a manner that a single backing-ratchet shall prevent the reverse movement of the main pinion-shaft frombeing communicated to either of said other shafts; fourthly, in the mode of yokingthe main pinion-shaft to the main drivewheel; and, fift-hly, in the mode of supporting and adjusting the main frame, all substantially as we will now proceed to set forth.

' In the drawings, A is the main drive-wheel, having an internal gear-rim, a, cast upon or attached to its grain side, and having a circumferential flange, a, proj ectingfrom the middle of its tread, in order to hold it in place on side hills. 0 is the platform, bolted or otherwise secured to the floor-plate D of the main frame and on a level therewith. E is the tongue connected to the inside corner of the main frame or platform, and having a diagonal brace-rod, e, extending to the outer corner of said frame; and F is the rake-standard, carrying raking and reeling mechanism of the character employed on the well-known Johnston Harvester, and therefore not necessary to be here shown or described.

Upon the floor-plate D of the main frame we arrange a casting, H, of the plan outline shown in Fig. 3, and having two vertical standards, i i, for the support of the main pinionshaft I, two similar standards, m m, for the support of the crank-shaft M, and one similar standard, a, for the support of the drivingshaft N, which operates the rakeshaft. The upper ends of the standards are made concave in the line of their respective shafting, and tubular shaft bearings or boxes 0 0 0 ,1'espectively, are mounted upon them, and strapped firmly down by staples p, which, countersunkin recesses on the outer side of the standards, extend down through the bases of the standards and through the floor plate or platform, and are provided with screw nuts beneath the frame, by which they can be tightened up, loosened, or removed, whenever desirable. The front end of the shaft N also bears in a socket or box, n, attached to the rake-standard below the bevel-gear wheel. The main pinion-shaft receives motion from the gear-rim a through a small pinion, i and communicates it to the crank-shaft by means of gear-wheels q q, and to the rake-shaft by means of gearwheels r 1", the wheels q 0' being cast in one piece in order that they may be thrown out of action simultaneously by a single backingratchet, W, as will be clearly understood from Fig. 1.

The tubular bearing of the main pinionshaft forms part of a yoke, Y, one arm of which extends to and is supported loosely up on the axle of the wheelA; or the axle of wheel A may be cast in tubular form as a part of the yoke. This holds the pinion always in gear, and at the same time permits the main frame to be raised andlowered or tilted to any required position. The arm 3 thus connected to the driving-wheel extends directly to the inner end of the tubular bearing 0, and is connected to the outer end of said bearing by a diagonal brace or braces, 3 cast in one piecea mode of construction which secures great rigidity and strength, prevents any cramping or bending of the pinion-shaft, and yet involves no great weight of metal.

The axle of the main driving-wheel A is a short shaft or stud, which. does not turn with the wheel. The drivers seat W is mounted upon and rigidly attached to the projecting end of the stud, as shown in. Fig. 1, on the side of the wheel opposite to the frame, while on the inner or frame side of the wheel a curved bracket, T, is rigidly secured to the opposite end of the stud and extends upward, terminating in a notched segment, t, which is bolted to the side of the lifting-bar U; or the wheel A may be mounted on a hollow stud forming part of the yoke, and the drivers seat may then be attached to the projecting end of an arm of the bracket T, which extends through the hollow axle. The forward end of the lifting-bar is connected by a slot and pin, a, to the side of the tongue, and its rear end is adjustably connected, by a curved rack-bar, V,

and sprin g eatch 'v, to the rear edge of the main frame or platform. A perforated bar, L, articulated to the front edge of the main frame or platform, extends upward, and is adjustably connected, by a pin, 1, to the short arm of a right-angled spring-catch lever, K, which is pivoted at the center of the segment t, and engages with the peripheral notches thereof, as

, will be understood by reference to Fig. 2.

By suitable adjustments of the two supportin g-bars V L the frame can be set at any re quired elevation and inclination, while the pitch of the cutter can be instantly changed and adjusted at any time by a movement of the spring-catch lever K.

With this construction the weight of the whole machine can be reduced without impairin g its strength or durability. The machine can be easily taken apart by any ordinary unskilled workman for storage, transportation, or repairs, and can be as easily put together again. It is well balanced and is completely adjustable for all purposes.

WVe claim as our invention 1. The main frame consisting of the parts D H Y, constructed in the form substantially as described.

2. The casting H, constructed with the vertieal standards 6 i, for the support of the main pinion-shaft I, the vertical standards on m, for the support of crank-shaft M, and the vertical standard a, for the support of the rake-operating shaft N, substantially as described.

3. The casting H, constructed, as described, with the standards 2' 5 m m, and n, in combination with the tubular bearings 0 o 0 and the floor-plate D, substantially as described.

4. The automatic backing-ratchet T in combination with the main pinion-shaft I, the crank-shaft M, and the rake-shaft N, substantially as described, for the purpose specified.
